Help wanted: web component to compute stamps about dnscrypt-proxy HOT 4 CLOSED

    stamp: function() {
      let props = (this.dnssec << 0) | (this.nolog << 1) | (this.nofilter << 2);
      let addr = this.addr.split("").map(c => c.charCodeAt());

      const dnscryptStamp = () => {
        let v = [0x01, props, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00];
        v.push(addr.length, ...addr);
        let pk = Buffer.from(this.pk.replace(/[: \t]/g, ""), "hex");
        v.push(pk.length, ...pk);
        let providerName = this.providerName.split("").map(c => c.charCodeAt());
        v.push(providerName.length, ...providerName);
        return `sdns://${URLSafeBase64.encode(Buffer(v))}`;
      };
      return dnscryptStamp();
    }
